Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for distributed processing in a vehicle networking system. A node in the vehicle networking system receives sets of processed sensor data from multiple nodes in the vehicle networking system. Each set of processed sensor data is generated using a first portion of a data processing algorithm on sensor data captured by different sets of sensors of the vehicle networking system. The node performs a second portion of the data processing algorithm based on the sets of processed sensor data received from multiple nodes, yielding a set of processed aggregated sensor data. The node may use the set of processed aggregated sensor data to provide a computer managed feature and/or transmit the set of processed aggregated sensor data to other nodes in the vehicle networking system.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a segmented ECF that includes multiple filter components to replicate an echo pulse response. The different filter components are used to replicate different portions of the echo pulse response. Each filter components can include filter coefficients of different sizes based on the portions of the echo pulse response that is replicated by the filter component. For example, a filter component that replicates a portion of the echo pulse response that includes a large reflection can include large filter coefficients suitable to replicate the larger reflection. In contrast, a filter component that replicates a portion of the echo pulse response that includes smaller reflections can include smaller filter coefficients that are suitable to replicate the smaller reflection. The output of each of the filter components is combined to replicate the full echo pulse response.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for efficient safety mechanism selection for achieving functional safety. A functional safety system automates the process of achieving a target diagnostic coverage level using recursive method to sequentially analyze each layer of a target environment and add additional safety mechanisms if a target diagnostic coverage level is not met. The functional safety system implements the additional safety mechanisms based on a ranking determined based on one or more selected parameters. The parameters may indicate a preference for achieving specified goals, such as higher efficiency, increased coverage, reduced cost, reduced area, and the like. The functional safety system adds the additional safety mechanisms based on the ranking, such as by adding the highest ranked safety mechanism, followed by subsequently ranked safety mechanism.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for protocol independent data unit forwarding. A packet forwarding system receives a data unit comprising a header byte string via an input port. The packet forwarding system parses the data unit based on a header type determined based on the input port, yielding a parsing output describing the header byte string of the data unit. The packet forwarding system updates a metadata item associated with the data unit based on the parsing output and determines a packet forwarding instruction for forwarding the data unit to a destination based on the metadata item associated with the data unit. The packet forwarding system forwards the data unit to the destination based on the packet forwarding instruction and the metadata item associated with the data unit.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for a hybrid physical layer that supports data communications using both Ethernet and ASA. Ethernet and ASA are communication standards that are commonly used in automotive environments; however, are not interoperable. The hybrid physical layer supports data communications using both Ethernet and ASA. For example, the hybrid physical layer may be configured into either a first mode of operation to support data communications using Ethernet or a second mode of operation to support data communications using ASA. Devices utilizing the hybrid physical layer can therefore be used with other components that utilize either communication standard.

The diagnostic coverage is determined based on the optimized netlist, thereby reducing the number of nodes that are injected with faults.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for configuration of time-sensitive networks. Time-sensitive networks utilize traffic shaping to provide for efficient and predictable flows of data through the network. A network configuration tool can be used to determine how data should be routed and shaped through the network towards its destination. The network configuration tool calculates the maximum burst size at an output port of a switch by analyzing groups of data flows that pass through the output port, rather than analyzing the data flows individually.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for achieving functional safety compliance using a recursive system layer analysis. A functional safety system uses a recursive method to sequentially analyze each layer of a target environment from a bottom layer (e.g., IP layer) to a top layer (e.g., system layer). If a target diagnostic coverage level is not achieved at a given layer, the functional safety system attempts to achieve the target diagnostic coverage level at the next layer based on the residual faults from the lower layer. At the top layer, the functional safety system may apply the context of the target environment to reduce the scope of the coverage analysis based on the given application. The functional safety system may also use the context of the target environment to the reanalyze the lower layers as needed.

Abstract: Disclosed are systems and methods for providing in-service testing using a redundant segment. A device (e.g., memory, filter, GPU) is implemented as multiple device segments. For example, a filter including 1024 taps may be implemented as sixteen smaller filter segments that include 64 taps each. A redundant segment that is of similar size to the device segments is used to provide in-service testing of the individual device segments. For example, the redundant segment is provided the same input as a device segment and the output of the redundant segment and the device segment are compared to determine whether the device segment is operating correctly. Multiplexers are used to cycle use of the redundant segment to provide in-service testing of each of the device segments. For example, the multiplexers can be configured into different modes to provide for testing of the various device segments.
